SCORPIA

Of the fifth exciting alex Rider mission, Anthony Horowitz says, 'This book fills in many of the details about Alex's past and finally reveals the truth about his father. And there are a couple of big surprises along the way....'

As always, Anthony's research has been exceptional. 'There's a secret weapon in Scorpia, called Invisible Sword. It may sound fantastical, but as far as I can tell, the technology exists and could be used at any time. I didn't make it up. That's what makes it so scary.'
